UNITED STATES HANNIBAL BERRYMAN', F CENTERVILLE'MONTA'NAQ ELECTRIC FIRE LIGHTER.

Application filed April 13, 1923. Serial No. 631,887.

To all whom it may concern:

Be it known that I, HANNIBAL BERRYMAN, a citizen of the United States, residing at Centerville, in the county of Silver Bow and State of Montana, have invented a new and useful Electric Fire Lignter, of which the following is a specification.

This invention aims to provide a novel means whereby combustible material on the grate of a stove or other heater may be ignited electrically, it being possible to adjust the electrode with respect to the grate bar so that a hot at spark will be assured.

It is within the province of the disclosure to improve generally and to enhance the utility out devices of that type to which the invention appertains.

lVith the above and other objects in view, which will appear as the description proceeds, the invention resides in the combina tion and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings Figure 1 shows in elevation, a device constructed in accordance with the invention, a portion of the frame work of the heater appearing in section; Figure 2 is a top plan wherein parts are broken away, a portion of the frame work of the heater appearing in section.

The numeral 1 marks the frame of a stove or other heater. The grate bars are designated by the numeral 2 and are journaled at 3 for rocking movement in the irame l. A tubular bearing 4- is secured in the frame II. in the bearing 4, a sleeve 5, preferably made of insulating material, is mounted tor longitudinal. adjustment and for rotary ai'ljustment. A clamj'iing device '18. such as a screw threaded into the bearing 4 and engages the sleeve 5 to hold the sleeve in adjusted positions.

The numeral 6 denotes an electrode com prising arms 7 and 8 disposed at an acute angle to each other. The angle in the electrode (3, "formed by the arms 7 and 8 is dcs ignatcd by the numeral 9. The arm 8 of the electrode 6 extends through. the sleeve 5. A nut 10 is threaded on the arm 8 of the electrode and serves to hold a conductor 11 on the arm, in abutment with a washer 12 on the arm, the washer bearing against the outer end of the sleeve 8. Not onl does the nut 10 hold the conductor 11 on t e arm 8, but, as well, the nut serves to move the arm 8 of the electrode lengthwise until the angle 9 of the electrode is bound against the outer end of the sleeve 5. Thus, the electrode and the sleeve are connected, for movement together in one piece. The conductor 11 may form an end of the windin of a spark coil, and the other end ofthe winding of the spark coil is represented by a conductor 14 connected to the frame 1 of the heater. In connection with the spark coil and the device as shown in the drawings. an alarm clock may be used, so as to operate the structure at any redetermined time, thereby making it possible for a the to be started with-out attention from an operator.

Because the arms 7 and 8 of the electrode 6 are disposed at an obtuse angle to each other, thearm 7 is given an inward inclination, and the upper end of the arm 7 lies relatively close to one corner of one of the grate bars 2, as shown in Figure 2. When the set screw 18 is loosened, the sleeve 5 may be shifted endwise in, the bearing 4: so as to adjust the distance between the upper end of the arm 7 of the electrode and the grate bar 2, measured in the direction of the axis of rotation of the grate bar. It is desirable that, as shown in Figure 2, the upper end of the arm 7 of the electrode be disposed closer toone corner of one grate bar than to the adjacent corner of the-other grate bar. in order that the part may not spread. and to jump to both grate bars, thereby producing a spark of decreased efliciency. Since the sleeve 5 is mounted to rotate for adjustmcnt in the bearing 4, the upper end of the arm 7 of the electrode 6 may be swung in an arc, so as to bring the upper end of the said ariu relatively close to one corner of one grate bar, as depicted in Figure hen the upper end of the arm 7 of the electrode 6 has been adjusted properly, the set screw 18 may be advanced so as to hold the sleeve 5, and consequently the electrode 6, in the proper position.

hat is claimed is:

In a device of the class described, a frame, a bearing mounted on the frame, a grate bar mounted on the frame, an electrode comprising augularly disposed arms, one arm terminating at a point adjacent to the grate bar, a sleeve mounted in the bearing for longitudinal adjustment and for rocking my own, I have hereto affixed my sigma movement, the sleeve receiving the other arm ture in the presence of two witnesses. of the elect-rode, file-ans for hOlLling Said other arm of the electrode in the sleeve, and 5 a tightening device carried by the hearing \Vitnesses:

and engaging the sleeve. R. C. MAoPHERsoN,

In testimony that I claim the foregoing D. R. WVHITINGToN.
